摘要： Disclosed is a process for forming an electrostatic latent image on a recording element having a dielectric layer superposed on a conductive electrode. In the first step of this process, the recording element and a xerographic sensitive element having a photoconductive layer also superposed on a conductive electrode are charged with the same polarity. In the second step, the photosensitive element is brought into virtual contact with the recording element so that the charged surface of the photoconductive layer in the photosensitive element is in face-to-face relationship with the charged surface of the dielectric layer in the recording element. In the third step, an external voltage is imposed between the two conductive electrodes, said voltage being of at least a magnitude for producing an electric field causing breakdown of minute air-gaps present between the contacted surfaces of the photosensitive element and the recording element and, before the completion of the external voltage imposition, an optical image is projected onto the photoconductive layer in the photosensitive element.

摘要： A transient mitigation system for a reactor includes: a reactor core isolation cooling system; and a high pressure flooder system including a high pressure flooder pump and a flooder valve. When the water level of the reactor water in the reactor decreases to a first predetermined water level, the reactor core isolation cooling system is activated to supply the cooling water into the reactor. When the water level in the reactor decreases to the first predetermined water level, the high pressure flooder pump is activated. When the water level in the reactor decreases to a second predetermined water level lower than the first predetermined water level, the flooder valve is opened to inject the cooling water into the reactor.

摘要： A head spray system of a reactor pressure vessel includes a head spray line, a check valve, a vent line, a vent line shut-off valve, and an interlock mechanism. The head spray line supplies cooling water into the reactor pressure vessel when shutting down a reactor. The check valve is set up on the head spray line. The vent line which is connected to the head spray line evacuates a noncondensable gas. The vent line shut-off valve is set up on the vent line, and is open during normal plant operation. The interlock mechanism closes the vent line shut-off valve when a certain period of time has passed from the time of detecting a supply of the cooling water to the head spray line.

摘要： A magnetic head assembly for a flexible magnetic disk drive unit has a magnetic recording and retrieving head for carrying out magnetic recording onto and retrieving from a metallic thin-film type flexible magnetic medium rotating about a center of the medium by coming into contact with the medium at a contact position, a first group of non-magnetic supporting pads arranged to support a plurality of positions of the flexible magnetic medium and disposed so as to surround the contact position, and a second group of non-magnetic suppressing pads in contact with a different plurality of positions of the flexible magnetic medium outward of the plurality of supporting positions so that the suppressing pads suppress any undulation of the flexible magnetic medium during rotation of the medium. The support pads and the magnetic recording and retrieving head may be formed with a recess, respectively, for trapping dust and other foreign materials, thereby preventing an accumulation of dust and other foreign materials between the head and the medium.

摘要： A magnetic recording disk cartridge includes a casing having upper and lower halves mated together to define a planar spacing in which a magnetic recording disk supported by a hub member is rotatably held, and fluctuation suppressing ring members are disposed within the casing to be axially spaced from one another via at least an outer peripheral portion of the magnetic recording disk. The fluctuation suppressing ring members aerodynamically maintain the magnetic recording disk at an intermediate position in the planar spacing of the casing during the rotation of the magnetic recording disk.
